Introduction

When we explore the structures of reality, we face the following puzzle: When we ordinarily encounter the world, we find it to be pre-divided into different objects of various, pre-given kinds. We feel that this is how the world really is and that it must be analyzed in terms of an object-predicate structure. However, how do we know that we are not misguided by the functioning of our brain and that structured we see are not in fact the result of our brain imposing these onto the world? How can we discern what is real from what is imposed by our cognition?
